Bite force quotient (BFQ) is a numerical value commonly used to represent the bite force of an animal adjusted for its body mass, while also taking factors like the allometry effects. The BFQ is calculated as the regression of the quotient of an animal's bite force in newtons divided by its body mass in kilograms. [ 1 ]
The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).
On 5 August 2011, a polar bear in the Norwegian archipelago of Svalbard attacked a party of 13 university students, who were undertaking an expedition organised by the British Schools Exploring Society (BSES), and were camped near the Von Post glacier, 40 kilometres (25 miles) from the settlement of Longyearbyen.

A grizzly bear had just taken a “good chomp right to the bone” on his leg. The bear dropped him. ... The most painful bite, the one that went “right to the bone” and elicited Burke’s ...
The polar bear species is declining because of disappearing Arctic sea ice. In 2021, scientists in Norway found polar bears were inbreeding as the species fights to survive.
Polar bears, particularly starving males, will hunt humans for food, though attacks on humans by female bears are rare. The earliest recorded account of a polar bear attack was written in 1595. It described a predatory attack on two people from Willem Barentsz's crew in the Russian Arctic. Between 1870 and 2014, out of 73 recorded polar bear ...
An animal bite is a wound, usually a puncture or laceration, caused by the teeth. An animal bite usually results in a break in the skin but also includes contusions from the excessive pressure on body tissue from the bite. The contusions can occur without a break in the skin. Bites can be provoked or unprovoked.
It is not certain how this force was used by the living animal; a study designed to determine how the genus fed discovered that among living bears, the lowest bite force belongs to the predatory polar bear, which feeds largely on blubber, and the highest bite force belongs to the giant panda, a herbivore which uses it to crush bamboo.
